"Myself and my mother have been ..."

Myself and my mother have been trying to contact the 2761245 number as recommended on the MRI/NHS website in order to obtain the visiting times for the ward in which my elderly aunt is receiving care. Since 10am this morning we've both being trying (I've made 5 attempts, my mother approx the same). No answer on the number - are there not enough staff to answer the phone or is it simply being ignored?? This poor service lets done an otherwise excellent hospital.
